45 ‑ 66 [Hz]
Frequency limit value
above which the power in-
crease takes place.
0 ‑ 100 [%/Hz]
Gradient by which the ef-
fective power increases.
Example - conversion from
static to gradient:
Static s = 5 % → Gradient k
= 1/(0.05*50Hz) =
40 %/Hz
45 ‑ 66 [Hz]
Frequency value at which
the power increase ends.
